Manual Door Unlocking:

Locate the Release Button

On the back of your key fob, find the release button. Press and hold it while pulling out the mechanical key.

Identify the Door Handle Cover

Look for a small plastic cover next to the driver side door handle. Insert the mechanical inside the rectangular slot at the bottom of the cover.

Access the Keyhole

Remove the cover to reveal a small hole. You may need to pull the door handle slightly to completely remove the cover.

Unlock the Door

Use the mechanical key to turn the keyhole counter-clockwise, unlocking the door.

Starting the Engine:

Enter the Vehicle

Once the door is unlocked, enter your Sportage.

Key Not Detected Warning

When you attempt to start the engine, a “Key Not Detected” warning may appear in the instrument cluster.

Touch Key Fob to Start Stop Button

Take the dead key fob and touch it to the Start Stop button.

Press Start Stop Button

Press the Start Stop button as you normally would when starting the car. Remember to press the brake pedal before hitting the button.

Successful Start

Your Sportage should start, bypassing the key not detected warning, even with the dead key fob battery.

Temporary Solution:

Replace the Key Fob Battery

Key Fob Battery Replacement:

Open the Key Fob

Locate the release button on the back of the key fob. Press and hold it while pulling out the mechanical key.

Use Mechanical Key to Pry Open

Insert the end of the mechanical key into the designated slot and twist to pry open the key fob.

You can also use a flat-head screwdriver or a plastic prying tool.

Inside, you’ll find the old battery. Carefully push it out of its compartment using your finger or a small tool.

Insert New Battery

Ensure the new battery is the correct type and voltage (3V CR2032). Match the positive and negative sides with the markings inside the key fob. Insert the new battery, making sure it’s properly seated.
